1683 -Users can use below the structure to fast debug the communication between RS485BL and RS485-LN. The principle is to put the PC in the RS485 network and sniff the packet between Modbus MTU and RS485-BL/LN. We can use this way to:

1685 -1. Test if Modbus-MTU works with PC commands.
1686 -1. Check if RS485-LN sent the expected command to Mobus-MTU
